Monitoring your applications and environment is a key capability of Hybrid Cloud Observability and is also available in a standalone module, Server & Application Monitor (SAM). Hybrid Cloud Observability and SAM are built on the self-hosted SolarWinds Platform.

Monitor with AppInsight for Active Directory

Key aspects of monitoring Microsoft Active Directory involve keeping a close watch on the application and service availability, and ensuring various performance metrics are checked against accepted thresholds.

AppInsight for Active Directory monitors physical and virtual Active Directory environments to identify issues about domain controllers, replication, and more. You can use this AppInsight application to track many key aspects of Active Directory by getting relevant performance data from the server level. You can also drill down into the datastore layer for performance data.

You can add AppInsight for Active Directory to domain controllers automatically during Discovery or manually via the Node Details view. After it's assigned to a node, AppInsight for Active Directory is considered an application and reports data to SAM through a set of component monitors included in the AppInsight for Active Directory template, such as:

Here are some ways to use the status and metrics provided by AppInsight for Active Directory:

  • File replication service: Identify replication failures or network issues that lead to slow replication rates between websites.

  • Directory services: Watch critical directory services to ensure your email and phone contacts are always synchronized.

  • Service outages: Monitor domain controllers continuously to prevent service outages. Diagnose performance issues by tracking CPU usage, connected users, failed logins, account lockouts, and more. Discover domain controllers on unmonitored nodes.

  • Dependencies: Troubleshoot Active Directory dependencies with widgets that show in-depth details about issues impacting performance.

A Microsoft Azure Active Directory API Poller template is also available. To learn more about API pollers, watch API Pollers: When SNMP Won't Cut It.

Note the following details about AppInsight for Active Directory:

  • If using a component-based SAM license, AppInsight applications consume licenses at flat rates.

  • Multiple instances of this database-intensive feature can impact performance. Consider limiting usage to a few key domain controllers. You can also adjust Advanced settings on individual nodes to boost performance by polling for LDAP data on a single domain controller in a domain, while continuing to gather replication details for all domain controllers in that domain.

  • When AppInsight for Active Directory is assigned to a specific node, SAM creates a DCApplication entity for the domain controller. Each DCApplication is grouped by the domain entity to which it belongs. SAM uses .NET Framework to poll data via a secure LDAP protocol for each domain. Gathered data includes the number of controllers, users, computers, replications, and site statistics.

  • AppInsight for Active Directory uses domain controller IP addresses instead of domain names for polling. LDAP components do not include the $DomainName parameter in configuration fields. This use of IP address enables different applications to get data from all monitored domain controllers in a single domain.

  • Like the other AppInsight templates, the AppInsight for Active Directory template includes several component monitors with default settings that cannot be modified due to dependencies. Also, you cannot add component monitors to this template.
